188 THE CONDOR Vol. XXVI 



Their manner of occurrence at Deadman Flat is plainly indicative of a tendency 

 to wander at the close of the breeding season, even though there is no established 

 migration route to be followed. It shows one way in which the species spreads, and 

 the manner in which the birds will pick out an isolated ranch for occupancy. I have 

 never seen an English Sparrow drop down into "wild" country in the manner in which 

 they constantly came to this and other nearby ranches. 



Astragalinus psaltria hesperophilus. Green-backed Goldfinch. A few seen from 

 time to time on the road between Deadman Flat and Flagstaff. Last noted October 17. 



Calcarius ornatus. Chestnut-collared Longspur. An abundant migrant. A single 

 bird seen September 18, three together September 20, and then flocks every day. Last 

 observed October 26. 



Rhynchophanes mccowni. McCown Longspur. One specimen collected October 

 16. A few others were seen in company with the abundant Chestnut-collared Longspur. 



Pooecetes gramineus confinis. Western Vesper Sparrow. Present when we ar- 

 rived, September 1, and in increasing numbers for about two weeks. By September 15 

 swarms of Vesper Sparrows arose everywhere one went in the grass land and rabbit- 

 brush. On September 19 their numbers had decreased markedly, and by October 1 they 

 were rather scarce. Last seen October 11. 



Passerculus sandwichensis nevadensis. Nevada Savannah Sparrow. None pres- 

 ent early in September. First seen September 20 and abundant for 'some days there- 

 after. On September 29 they were swarming in the grass land and in cultivated 

 fields but nearly all were gone on the 30th and none was seen later. Two birds were 

 collected, both distinctly referable to nevadensis. 



Chondestes grammacus strigatus. Western Lark Sparrow. Seen in fair abun- 

 dance early in September, mostly along the road between Deadman Flat and Flagstaff. 

 They disappeared early in October. 



Zonotrichia leucophrys leucophrys. White-crowned Sparrow. 



Zonotrichia leucophrys gambeli. Gambel Sparrow. 



Two specimens of the subspecies leucophrys were shot on September 21, the first 

 arrivals. White-crowned sparrows of one kind or the other were seen occasionally 

 from then on, never in abundance. On October 18 the last were noted; several seen 

 that day were definitely recognized as gambeli. 



Spizella passerina arizonae. Western Chipping Sparrow. Seen from the lower 

 part of the yellow pine belt downward. Abundant during September and in lessening 

 numbers early in October. Last seen October 17. 



Spizella breweri. Brewer Sparrow. In fair abundance on Deadman Flat during 

 September. Exact time of departure ■\j(as not noted, but no observation of this species 

 was recorded in October. 



Junco hyemalis hyemalis. Slate-colored Junco. A male bird seen near the lower 

 edge of the yellow pine belt (about 7500 feet altitude) on October 27, in a small flock 

 of shufeldti and eaniceps. 



Junco oreganus shufeldti. Shufeldt Junco. Arrived October 8. Seen there- 

 after in fair abundance, mostly in the pinon-juniper belt, but also upward to the lower 

 edge of the yellow pines. 



Junco mearnsi. Pink-sided Junco. First seen October 17 at about 7500 feet 

 altitude. A few noted at irregular intervals during the rest of my stay, usually single 

 birds in flocks of shufeldti and eaniceps. 



Junco eaniceps. Gray-headed Junco. An adult female collected October 1 on 

 Deadman Flat was the first migrating junco of any kind to appear. By the middle of 

 October eaniceps was present in fair abundance, in the pinon-juniper belt to some 

 extent, but in greater numbers in the yellow pine belt. Flocks of juncos were fre- 

 quently encountered composed of as many as fifty or sixty individuals. Nine-tenths of 

 such a flock would consist of eaniceps and shufeldti in about equal numbers, with a 

 few mearnsi and perhaps an occasional hyemalis. 



Junco dorsalis. Red-backed Junco. The breeding species of Junco. Found by 

 me in the same sections as are designated by Merriam, "throughout the upper levels 

 of the pine plateau region and in the balsam and spruce belts." One specimen was 

 collected in juniper woods September 28, accompanied by another that was supposed 

 to be of the same kind. This was the only occasion on which dorsalis was seen below 

 the yellow pine belt. When the migrating northern juncos arrived, the mixed flocks of
